孙悟空被砍脑袋那一集是斗法降三怪那一集。是说孙悟空师徒四人到了一个国家发现所有的寺庙都破烂不堪，看不到和尚的踪影，后来看到大街上有官兵押着很多和尚在做苦力盖道观。
后来才知道这个国家有三个妖精化成道士作威作福，孙悟空最后在皇上的见证下与三妖怪斗法，和虎力大仙斗法的时候砍下了脑袋。
The episode of Sun Wukong's beheading is the episode of fighting the three monsters. That is to say, when the four disciples of Sun Wukong arrived in a country, they found that all the temples were dilapidated, and there was no sign of monks. Later, they saw officers and soldiers on the street holding many monks as coolies to build Taoist temples.
Later, I learned that there were three goblins in this country who turned into Taoist priests to bully and bless. Sun Wukong finally fought with the three goblins and cut off his head when fighting with the tiger power fairy under the witness of the emperor.
